Comments
a) The
S.W. Amplitude
must be greater than
Step E
(which is the potential step
height for the staircase potential wave form).
b)
Sampling Points
is the number of current samples taken and averaged at the
end of each half-cycle. The 3 current sampling options are:
i) 256 samples taken and averaged over 1 line cycle (maximum
S.W.
Frequency
= 15 Hz).
ii) 16 samples taken and averaged over 1 msec (maximum
S.W. Frequency
= 250 Hz)
iii) 1 sample taken (maximum
S.W. Frequency
= 2000 Hz).
The maximum frequency for each option is such that the sampling time is no
longer than 1/2 of each half-cycle. The option is selected by the software.
c) The scan rate (mV/s) is the product of the
S.W. Frequency
and
Step E
.
d) The sample interval is equal to
Step E
.
